Exchange itinerant

Yb2Ni,2P7 LusFefjP Intermediate valence (Yb) Weak itinerant exchange 3.9 Yb " Zeppenfeld and Jeitschko (1993) Reehuis and Jeitschko (1989), Raffius et al. (1991)... [Pg.412]

We have used the basis set of the Linear-Muffin-Tin-Orbital (LMTO) method in the atomic sphere approximation (ASA). The LMTO-ASA is based on the work of Andersen and co-workers and the combined technique allows us to treat all phases on equal footing. To treat itinerant magnetism we have employed the Vosko-Wilk-Nusair parametrization for the exchange-correlation energy density and potential. In conjunction with this we have treated the alloying effects for random and partially ordered phases with a multisublattice generalization of the coherent potential approximation (CPA). [Pg.57]

As far as magnetic phenomena are concerned, if the system is all in the lower subband (i.e. localized) then the treatment for locahzed spins holds, and exchange forces between them may provoke eventually ferro- and anti-ferromagnetism. If the system is itinerant in the unsphtted band then treatments of magnetism in narrow bands such as Stoner s are valid. Hubbard derives also a condition for collective magnetism which is similar to the Stoner s one ... [Pg.40]
